This is a developement series (requested by Petr Vorel) that handle
symlink01 split, which has been already merged in the master branch.

In this series we face the next part of symlink01 split that
includes stat04, lstat03, open15 and chmod08.

Signed-off-by: Andrea Cervesato <andrea.cervesato@suse.com>
---
Changes in v4:
- stat04: use asprintf
- stat04: remove unlink() from cleanup
- lstat04: remove unlink() from cleanup
- Link to v3: https://lore.kernel.org/r/20240710-stat04-v3-0-c68a2324ad94@suse.com

Changes in v3:
- stat04: smarter cleanup
- lstat03: smarter cleanup
- open15: fix algorithm, read/write from/to symlink
- Link to v2: https://lore.kernel.org/r/20240709-stat04-v2-0-2693a473a2ab@suse.com

Changes in v2:
- update TST_EXP_EXTR to support stringification
- call stat() inside the test run() routine
- call lstat() inside the test run() routine
- simplify chmod08
- simplify open15
- Link to v1: https://lore.kernel.org/r/20240702-stat04-v1-0-e27d9953210d@suse.com

Andrea Cervesato (4):
      Add stat04 test
      Add lstat03 test
      Add chmod08 test
      Add open15 test

This test has been extracted from symlink01 test and it checks that
stat() executed on file provide the same information of symlink linking
to it.

This test has been extracted from symlink01 test and it checks that
lstat() provides the right information, according with device, access
time, block size, ownership, etc.
